ASAP Find the missing angle values show work. complete sentence

A. Angle a = _
b. angle b = _
c. angle c = _
d. angle d = _
e. These angles together make a complete rotation/a circle. What do you get when you add all the angles together. What does this number have to do with a circle?

Step-by-step explanation:

Angle a = 35°

Angle b = 40°

Angle c = 35°

Angle d = 70°

When you add all the angles together, you get 360°. This number has to do with a circle because 360° is the total number of degrees in a circle, half of a circle would be 180°.

Hope this helps!

∠a = 35

∠b = 40

∠c = 35

∠d = 70

Step-by-step explanation:

∠b =  40   {Vertical angles are congruent}

∠d = 70  {Vertical angles are congruent}

∠1 = ∠ a

∠2 = ∠c

∠1 = ∠2

So, ∠1 =∠2 = ∠a = ∠c

70 + 40 + ∠a + ∠2 = 180   {Straight line angle}

110 + 2∠a = 180              {∠a =∠2}

         2∠a = 180 - 110

          ∠a = 70/2

∠a = 35

∠1 =∠2 = ∠a = ∠c = 35

e) When we add all the angles, we get 360.
